rainThe rainfall on a certain day is 4.3 cm. Find in litres, the volume ofwater which fell on a levelled field of area one hectare of land on that day

Answer»

Area of field = 1 hectare

Height of rainfall= 4.3 cm

Volume Of Water = Length×Breadth×Height

Area of field = Length×Breadth= 1 hectare

1 Hectare = 100000000 cm²

Volume of rainwater= Area× height

Volume = 100000000 ×4.3= 430000000 cm³

1 m³ = 1000000 cm³

430000000 /1000000 = 430 m³

1 m³ = 1000 litres

430 m³ =430000 litres of water

Hence, 430000 litres of water will fell on a levelled field of area of one hectare of land on that day.
